Reflective Windows Exterior Ray Trace

Recommended Posts

Hello,

I am working on an exterior ray trace, and I would like the windows to be slightly reflective instead of transparent. What is the right material and properties for this look? I tried to make the glass a mirror, but it turned out really dark in my ray trace. I attached a picture (not mine) that shows the look I am going for. 

I am using Chief X12. 

thank you!

In the 'Define Material' box, set the glass to transparent/crown glass (in the properties tab), then darken the glass a bit in the material color section of the pattern tab (try various shades of grey). Also, be sure there are no interior lights turned on and set the interior ambient to zero.

Thank you, I wish there was a reflectivity setting I could adjust. I will mess around with the grey shades a bit more.

You may also want to try experimenting with different settings for refraction (in the properties panel when set to 'Transparent').

Thanks, I will play with that too. Some of these words are new to me and confusing, haha. It takes a lot of trial and error.

Post your plan file and I'll send you back a rendered image in a few minutes.

Thanks, here is a plan along with the ray trace I have done. I'm pretty happy with it except for the window glass and the grass. I put window treatments in to hide the interior while still allowing some transparency.

You're off to a good start, here are a few adjustments you can make:

  • Experiment with different sun angles
  • Decrease the sunlight to about 15,000 Lux (if you are doing a PBR, increase the brightness)
  • In ray-trace edit, set Ambient Occlusion to .50 min - 2.5 max (as a starting point)
  • I also like to keep the ambient lighting to a minimum (it can make a scene look flat)
  • Specify your background image (Enable Env. Light)
  • Turn on Caustics (Advanced tab)

Also, for the camera:

  • Increase height to 96"
  • Get rid of the camera tilt, it should be level
  • Narrow the field of view to around 40 degrees

The rest is adjusting your materials and properties (very important!).

 

Hope this helps- Eric

thanks so much! You listed many things I have never done before, so this is a good learning experience. There is so much to know! thanks

      Good morning,
       
      I am still pretty new into Ray Tracing both CPU and GPU. I seem to have a pretty good grasp on the interior GPU with playing around with lighting / sun light etc.
      However - the exterior Ray Tracing, you can see it looks to be foggy? I have attached before / 100 passes / 200 passes.
       
      Any help would be greatly appreciated. Also not sure how to make the ground look more realistic? I tried adding small shrubs and rocks. 
       
      Thank you!

      Hi All!
       
      I am a pro-x14 user and can't figure out why I am loosing my backdrop when raytracing through multiple pieces of glass. In this case I am going through two glass shower walls then a window as you will see on the left side of the rendering.....on the right side the windows/ backdrop are displaying correctly. 
       
      I looked for existing threads on this but couldn't located any. Is there a simple fix I am missing besides painting the window glass with the background or using photoshop?
       
      Thanks for the help!

      I'm looking to see if there is a way to separate the material between the frame and the reveal of a window (or door).
      When painting the frame it also paints the reveal the same material, and visa versa.
      I have been a long time Chief user but never found a solution - so hoping someone has a good trick. Using X13 currently.
       
      Thanks in advance!

      I am very perplexed by the lack of light in the interior physically based ray tracing camera. They always appear to be taken with all the interior lights off. 
      What I have tried so far:
      - adjusting the camera exposure and brightness
      - adding lights and light sources
      - increasing the maximum number of lights on
      - adjusting the sun angle, etc.
       
      I can NOT figure out how to make the interior rooms brighter!! I would LOVE if someone can help! This is a very powerful tool if it can be rendered correctly
       
      both attached images have light sources that are turned on

      Hello,

      I am trying to find the best way to model a Georgian window, with an angled inset into the wall's thickness, and a window along the inner edge (see the attached image). Note that this isn't a box window - there is no "bump out" - the window is set into the wall. I thought about using a wall niche, but I do not know how to create the angle. 

      Any suggestions would be greatly appreciated.
